TILE-MOLD.

No. sashes.

Application filed July 5, 1907, Serial No. 382,271.

To all whom it may concern:

Be it known that I, JOHN H. STEWART, a citizen of the United States ofAmerica, and a resident of Waterloo, Blackhawk county, Iowa, haveinvented certain new and useful Improvements in Tile-Molds, of which thefollowing is a specification.

My invention relates to improvements in tile-molds, and the object of myimprove.- ments is to provide an improved cylindrical two-part moldhaving resilient walls, and whose parts have reversible hingeconnections, and also convenient means for drawing together and securingto each other the registering free edges of the semi-cylindrical partsof said mold. This object l. have attained by the means which arehereinafter described and claimed, and which are illustrated in theaccompanying drawings, in which Figure 1 is a front elevation of myimproved tile mold showing the securing catches and registering means.Fig. 2 is a rear elevation, showing my reversible hingeconnections. Fig.3 is an elevation, showing the two semi-cylindrical parts of the moldfrom the inside and as separated from each other to the widest extent.

Similar numerals refer to similar parts throughout the several views.

My tile-mold is particularly designed to be used as the outside formerfor tiles made of a material of a soft yielding consistency, such ascement mixed with sand. It is composed of two semi-cylindrical parts, 1and 2, which when placed. so as to have their vertical. edges incontact, and secured together form a cylinder. At the rear the plates 22and 23 are fastened to the parts 2 and 1 respectively along theirvertical edges, such plates having flanges 24 and 25 respectively whichare parallel to each other, but spaced apart. The plates aforesaid aresecured to the parts 2 and 1 by means of bolts 20 and nuts 21. Theplate-flanges 24 and 25 have near their ends projecting and engagingmembers 17 and 18, as shown in Fig. 2, the member 17 in each case beingreceived between the members l8 and all having registering aperturesPatented July 13, 1909.

Renewed May 8, 1908. Serial No. 431,697.

in which pintles 19 are inserted to form hinge-connections. Each of theplates has a single member 17 at one end and a two-part member 18 at theother end, and by this arrangement, the two platc-eonnections areinterchangeable and. reversible.

At the front, the parts 1 and 2 have facingplates 3 and 6 along theirvertical edges respectively, with flanges 4 and 5 which are adapted tocontact with each other when drawn together. These flanges are recessedat the points indicated by the numeral 26, such recesses being adaptedto receive the tongues 10 on the other contacting flange to cause suchflanges to truly register with each other throughout. Each flange hasthumbpieces 11 which are set opposite to each other and used asflngerholds by which to draw such flanges together to overcome theresiliency of the walls of said semi-cylinders. On a stud 13 is pivoteda latch 15 having a handle 12, the latch 15 being recurved in such amanner as to have its point pass beyond the dead-center when turned overto contact and clutch the catch 14, as shown in Fig. 1.

The walls of the semi-cylinders l and 2 are constructed of thin metallicplates and are resilient, so as to tend to spring a certain distanceapart, when the latch 15 is detached from the catch 14. The saidsemi-cylindors are furnisl'ied with parallel inwardly openingcorrugations 16, and. when said mold has been secured together and. thetile-material deposited. within it, such material fills the concaviticsof the inner sides of the corrugations, and holds the tile securelytherein, so the mold with the soft formed tile within it may be movedfrom place to place without said tile slipping out.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

A tile-mold composed of separable halves of resilient material providedwith inwardly opening parallel corrugations and having registering edgesat front and rear, the rear edges being hinged together, and the frontedges provided with contacting plates having parallel flanges, a tongueprojecting from beyond the dead-center to secure said sepeach flangeadapted to enter and contact arable halves together. 10 with a recessopposite to it on the other Signed at Waterloo, Iowa, this 15th dayflange, finger-hold projections on each flange of June, 1907. setopposite to each other, a catch on one JOHN H.
